Types of Android Intents
There are two types of intents in android: implicit and explicit.
1) Implicit Intent
Implicit Intent doesn't specifiy the component. In such case, intent provides information of available components provided by the system that is to be invoked.
For example, you may write the following code to view the webpage.
Intent intent=new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("http://www.javatpoint.com"));
startActivity(intent);
2) Explicit Intent
Explicit Intent specifies the component. In such case, intent provides the external class to be invoked.
Intent i = new Intent(getApplicationContext(), ActivityTwo.class);
startActivity(i);
